lowermost position, and. at the same time air from the upper end free to exhaust through pipe 27, port 30 in the valve plug and exhaust passage 31. It

the valve plug 29 is shifted to the'lctt or anticlockwise one quarter turn it will read ily'lbe seen that Conditions will be reversed and air will pass from pipe 24lthrough port 2Y8'into pipe 27 and thence to upper side of the piston, when thepiston will be forced down, "thus raising the agitator arm to extreme upper position, the air in the lower end of the :ylinder being exhausted through pipe 26, port 30 to atmosphere through port 31. r

It will be observed that by pivotingthc agitator arm outside the receptacle. 1, all operating parts are free from contact with the fuel with the exception of the end 13 of I the agitator arm, and therefore there is no obstruction offered to the operative parts by the fuel, and all parts may be readily inspected and repaired at any time. The slot 14 in the wall 12 is out directly above the hopper 7, so that fuel sifti1igtln'ougli the slot falls intothe hopper 7 r and is not wasted.

The operation of the mechanism is follows: "When fuel ceases to passthrough the chute 8 it is, an indication that the fuel has become arched above the, passage into the chute. hen such a condition arises the operator by agitatingthe coalv above the passage 2 A continued oscillation olthc agitator arm is caused by movingthe valve handlef32fback and forthuntil' the desired effect is produced.

It is quite obvious that valvemechanism could be employed thatwould cause the piston 17 to reciprocate continuously as long as airwas' supplied to the cylinder, in which event the operator would be required to open a valve to opefrate the piston andleave of the cylinder is.

moves the valve handle, 32 to the. left causing thepiston 17 to be forced down and; the agitator arm to be forced up, theresuch valve open as long as oscillation of,

lVhat I claim is:

1. The, combination. with a fuel receptacle having a discharge opening through its lower side, a'closure means for theopening and an. inclined wall extending upwardly and tothe rear from said openin and pro vided with a slot, a \l-shaped agitator pivoted at one end to the inclined well and provided at such end with an operating lever and having its other end working through said slot, and means for swinging,

the agitator about itsipivot independently of the actuation of the said closure means, the said. agitator beingihounted so that its agitating arm in its upward movement swings longitudinally of the inclined wall and away from said wall.

2. The combinatipn with a fuel receptacle having a discharge opening, through its lower side, closure means for the opening and an inclined wall extending upwardly and to the rear from said opening and providcd with a slot, a V-shaped a itator pivoted at one end" to theinclined wall and provided at such end with an operating lever and having. its other end working through said slot, and means for swinging the agitator about its pivot, independently of the actuation of the said closure means,

the said agitator being mounted, sothat its swmgs longitudinally or; the inclined wall and away from said wall, and" the said agitator bein .formedfromya fiat metal plate: working edgewise and having its working Goplel. of this patentlmay be obtained for five cents each, by addressing the Commissioner of'latenfl,
